ACE711E
2A, Step-Up DC/DC Regulator 20V
Description
The ACE711E is a high efficiency step-up converter with an internally integrated 20V power MOSEFT.
It runs with an optimal 1MHz frequency that enables the use of small external components while still
providing the best efficiency. It can drive up to 2A output current. The incorporated true PWM-Diming
feature through EN pin enable one further digitally program the output voltage lower. For maximum
protection, the ACE711E has an OVP protection feature that prevents the output voltage exceeding the
maximum rating of the ACE711E and the output cap during open conditions.
